2.0 2.0 Theory of OperationTheory of Operation
The DCX disconnect product family includes multiple amperage ratings and installation mounting schemes to provide a
DC or Battery source disconnect device for use in Telecom +24 or -48VDC systems as well as solar-alternate energy
or other DC applications. The primary application for the DCX system is to provide over-current protection for battery
sourced equipment and wiring. The secondary function is to provide a service disconnect in order to maintain batteries or
to shut down the battery source connection in an emergency.
2.1 2.1 Circuit Breaker Trip RatingsCircuit Breaker Trip Ratings
The DCX product family includes circuit breaker trip ratings of 400, 600, 800, 1000, and 1200A. The electrical
conguration allows for both positive and negative connected systems as factory congured options. The DCX system
includes a circuit breaker or switch, an internal input and output copper bus structure, a steel inner housing, a circuit
board, and a ame retardant plastic outer housing.
